The History Guide, originally developed and located at Goettingen State and University Library since 1995 within a project funded by the Deutsche Forschungsgemeinschaft (German Research Foundation) and publicly accessible since 1997 cooperates with the InformationsWeiser Geschichte of the Bavarian State Library since 2001. This cooperation has been enlarged within the project Clio-Online and will be transformed in 2003 in a so-called Network Subject Gateways History.
